Rustmästare is a former Swedish rank that literally means the one responsible for the armory.

Rustmästare was used, among other things, as a designation for officer rank in the artillery during the 16th century and as a non-commissioned officer title in the infantry from around 1615 to 1835.

[1] Rustmästare was originally a non-commissioned officer rank and the holder of the rank was responsible for the care of the armory, weaponry and ammunition within a company.

Prior to 1972, military personnel were divided into three categories Underbefäl (non-commissioned officers), Underofficerare (warrant officers) and Officerare (commissioned officers).

Furir, överfurir, sergeant and fanjunkare were removed as a professional ranks.
